No words of wisdom, just empathy. (Was married 15 years...humph. Enough said).
FWIW, I've always wanted a cyclocross bike. Riding a CX is being a kid again. With a fancy road bike, you are limited to nice surfaces. And you have to be more careful with the bike. The steel Schwin Le Tour I grew up on might as well have been a XC for the way I treated it. The thing was bomb-proof. I remember riding up gravel piles.
If you really wanted to make your proposed CX a do anything bike, you could get a second set of nice road wheels with slicks. Maybe hand-built. Then the only difference would be that you had more reliable brakes. (More or less.

).
